Flight jet simulator are games that provide an environment that is similar to those that jet fighters experience in real life. The simulators that the military uses are much more complex and realistic than those you can use on your computer but you can still have a lot of fun if you cannot afford flying lessons but still want the thrill.
The very first simulator for a computer was developed by Microsoft in 1982 though since then they have greatly improved. The big breakthrough in gaming simulators was when PlayStation 1 released its Air Combat. Today these programs specialize in certain time periods, aircraft and even specific battles.
The three main combat flight simulators available from Microsoft include Combat Flight Simulator WWII Europe series, Combat Flight Simulator 3: Battle for Europe and Combat Flight Simulator 2 WWII Pacific Theater. If you are looking for the most realist software then you should check out the IL-2-Sturmovik series available from Ubisoft.
These jet combat simulators are all based on specific time periods as well as the types of jets you can fly. Many times you can even find specific battles from history. There are not many programs available from WWI but two options include the Red Baron and the Ride of Flight: The First Great Air War.
The many different programs from WWII include the Combat Flight Simulator series, Battle of Britain II: Wings of Victory, IL-2-Surmovik 1946, Aces Over Europe, B-17 Flying Fortress, 1942: Pacific Air War and Aces High. There is one program from the Vietnam war available, Flight of the Intruder, and one program from the Korea War, MiG Alley.
These programs from history allow you to fly several different planes from the time period. While flying these plans you will learn the advantages and disadvantages of flying the different models as different planes will have different fighting styles. These types of simulators are called survey simulators.
